RAILWAY-FROG.

Application filed. December 29, 1917, Serial No. 209,464. Renewed September 6,

To all fui/tom it may concern:

Be it known that 1, BENJAMIN J. Mon- GAN, a citizen of the United States, and resident of Des Moines, Polk county, Iowa, have invented a new and useful Railway- Frog, of which the following is a specification.

The object of this invention is to an improved construction for frogs.

A further object of this invention is to provide an improved construction for railway frogs provided with movable wing rails which are actuated by the flanges of car wheels passing over them.

A further object of this invention is to provide a simple and durable frog of the class described which will be cheap of construction, long of life and which will not readily get out of order.

A further object of this invention is to provide improved means for connecting a pair of wing rails for movement of one from the other.

A further object of this invention is to provide improved means for limiting lateral movement of wing rails on a bed plate.

A further object of this'invention is to provide improved means for mounting wing rails on a bed plate.

A further object of this invention is to provide improved means for mounting a point on a bed plate.

My invention consists in the construction, arrangement and combination of elements hereinafter set forth, pointed out in my claims and illustrated bythe accompanying drawings, in which# i Figure 1 is a side elevation and Fig. 2 a plan of my improved frog. Fig. 3 is a side elevation of the bed plate with the wing rails and point removed. Fig. 4 is an end elevation of the bed plate, taken from the provide railway point end. Fig. 5 is a side elevation and Fig. 6 a plan of the point detached, and

Fig. 7 is an end elevation showing the shape of the outer end of one of the forked members of the point. f Fig. 8 is a plan, Fig. 9 a side elevation, and Fig. 10 an outer end elevation, of one of the wing rails detached, on a slightly reduced scale.

1n the construction of the device as shown the numeral 15 designates generally.a bed plate which is formed in one piece from metal by molding or casting. The bed plate 15 is adapted to be secured to railway ties Specification oi'. Letters Patent.

(not shown) in any suitable manner, and is provided at one endwith divergent chairs 16 each adapted to receive and be secured to end .portions of crossing rails (not shown) of railway tracks. The bed plate 15 also is provided with raised portions or seats 17 adapted to receive and support the wing rails, hereinafter referred to. The bed plate 15 preferably is not formed solid in its base portion between the chairs 16 and between portions of the seats 17, but is partially of open or skeleton construction and formed with integral connecting crossbars 18. Adjacent the outer ends of the seats 17 the bed plate 15 is formed with integral, laterally and outwardly projecting extensions 19 formed with vertical pivot holes. Wing rails 20, 21 are mounted on the seats 17 and at one end each of said wing rails is formed with a lateral, outwardly projecting extension 22, having its top surface depressed relative to or on a lower plane than the tread surface of said wing rail, from which extension a pivot pin 23, integrally formed, projects downwardly through the pivot hole of one of the bed plate extensions 19. At the opposite end from the chairs 16 the bed plate 15 is formed with an end-opening, tapered seat 211 (Fig. 4) of inverted T-shape in crosssection in which a point' 25 is adapted to be mounted and suitably secured, between end portions of the raised portions or seats 17. At its outer' end the point is formed of divergent members of a fork, 25a, adapted to abut end portions of and be secured to crossing track rails. The point 25 is formed with enlarged tread and base portions connected by a relatively thin web, the base and web portions being fitted to the seat 24; and the divergent members y25a thereof preferably are of typical rail construction, embodying a base, web and ball, and the ends of the bases of said members are shouldered and abut the end of the seat 24 of the bed plate.` The wing Vrails 20,21 embrace and are adaptedtocontact selectively with opposite sides of the point 25.

ln order to connect the wing rails so that one may be moved conjunctively with the other, each of said wing rails is formed intermediate of itsends with a downwardly projecting lug 26 formed with a slot 27 (Fig. 9), and the bed plate is recessed to admit said lugs. A connecting member 28 connects the lugs 26 of the wing rails, and

Y loosely laterally 1- in material and lessens the may comprise a bolt or a bar or plate with reduced end portions extending through the slots 27 and suitably secured. Adjacent the lugs 26 the bed plate is formed with upwardly extending stops 29, 30 outside of and adapted to limit lateral movement of the wing rails, and said stops are formed with apertures 31 for the connection of yielding pressure devices (not shown) of common form adapted to exert moving pressure on the wing rails. Adjacent the point 25 the bed plate 15 is formed with upwardly projecting stops 32, 33 also adapted to assist in limiting lateral movement of the wing rails. The stops 32, 33 are formed with enlarged openings 34 through which project extending lugs 35 formed on and near the ends of the wing rails 20, 21. curing the wing rails to the bed plate and yet permitting the necessary lateral movement. v

In use, when one wing rail is contacted and forced aside by the flange of a passing car wheel, the other wing rail is drawn by the connecting member 28 into close contact with the point 25 to provide a continuous track for the car wheel. The offsetting of the pivot pins 23 of the wing rails reduces the wear thereon as the weight of the passing cars is not directly over said pivots, and the forming of the extensions 22 with top surfaces at lower elevations than the tread surfaces of the rails prevents contact of said extensions and the pivots by so-called blindV flanges on drive wheels. The provision of apertured stops 32, 33 near the free ends of the wing rails, and lugs projecting laterally from said wing rails and slidable through said stops, prevents accidental displacement of the wing rails which might occur when loose brake chains engage and catclron said wing rails. The skeleton construction of the bed plate saves i weight ot the complete device.

I claim as my invention- 1. In a railway frog, a bed plate formed with laterally spaced seats adapted to support wing rails, said bed plate being formed with a base of skeleton construction comprising spaced cross pieces connecting said spacedl seats.

2. In a railway` frog, secured to said bed rails embracing said at one end with an integral outwardly projecting lateral extension reduced in height relative to the wing rails and having their upper surfaces on lower planes than the tread surfaces of said rails, said lateral extensions being pivoted independently of each other to said bed plate, stops on said bed plate limiting outward movement of said wing rails, said stops being arranged in pairs a bed plate, a point plate, a pair oii wing Thus provision is made for lirmlv sepoint and each formed spaced longitudinally of the bed plate, and a member delinitely connecting said wing rails between the members of one pair olf said stops.

3. A railway frog, comprising a bed plate, a point formed with enlarged upper and lower portions connected by a relatively thin web, said bed plate being formed with a tapered end-opening seat corresponding in cross-section to the base `and web portions of said point, the point having .itsI base and web portions mounted in said seat and its upper or tread portion projecting thereabove, said point also being formed with divergent members ofV a fork adapted to be secured to track rails, said divergent members being of typical rail construction and having shouldered bases adapted to abut said bed plate adjacent said seat, anda pair of wing rails independently pivoted to the opposite end portion of the bed plate and embracing and adapted Vto coact with the tread portion of said point.

4. In a railway frog, a bed plate, a point secured to said bed plate, a pair of wing rails embracing said point and each formed at one end with an integral outwardly projecting lateral extension reduced in height relative to the wing rails and having their upper surfaces on lower horizontal planes than the tread surfaces of said rails, said lateral extensions being pivoted independently of each other to said bed plate, and stops on said bed plate limiting outward movement of said wing rails, sai stops being arranged in pairs spaced longitudinally of the bed plate, the members of one, pair ot said stops being formed with registering openings, said wing rails being formed with outwardly extending members adapted to traverse said openings.

5, In a railway frog, a bed plate. a point secu-red to said bed plate, a pair of wing rails embracing said point and each formed at one end with an integral outwardly projecting lateral extension reduced in height relative to the wing rails and having their4 upper surfaces on lowerplanes than the tread surfaces of said rails, said lateral extensions being pivoted independently of each other to said bed plate, stops on said bed plate limiting outward movementV of said wing rails, said stops beingarranged in pairs spaced longitudinally of the bed plate, the members of one pair of said stops being formed with registering-openings, said wing rails being formed 'with outwardly extending members adapted to traverse said openings, and a member definitely connecting said wing rails between the members of one pair of said stops.
